Why does a Cat Matter?
===
# Cat
* Not a Picture, Not a Video, Not a Flash animation
* It is HTML and CSS, like ALL web pages
# Web Pages: HTML+CSS
* HTML: describe content and structure of a web page
* CSS: describe the style of how content should be displayed
* Browsers: computation needed to decide how web pages look like.
